AI-Guidance for DVT exams

AutoDVT enables any healthcare professional to perform Deep Vein Thrombosis (DVT) scans at the point of care. It uses artificial intelligence to guide the user through the current gold-standard procedure, a full-leg ultrasound examination.


Note: Not FDA/CE Class II approved. Currently in clinical trials. See ADVENT study information here.

What is DVT

Deep Vein Thrombosis (DVT) is a blood clot within the deep veins of the leg. This can be potentially fatal if parts of the clot breaks off, travels through the body and becomes lodged in the lungs – this is called a pulmonary embolism (PE).

The Problem

While DVT and PE combined are the number one cause of preventable hospital death, the current diagnostic pathway is slow and inefficient. Patients often wait hours or days for test results.

AI Solution

AutoDVT enables any healthcare professional to collect DVT exam data for diagnosis. This can vastly improve access to care and patient outcomes. An AutoDVT exam takes between 5 and 15 minutes using only a handheld device and a mobile phone.

AutoDVT Improves the Clinical Pathway

AutoDVT significantly improves and speeds up the DVT clinical pathway.

How It Works


Conduct a gold-standard DVT exam with live AI-guidance. Intuitively identify the correct anatomy and probe positioning, allowing fast and accurate data collection without direct oversight.


Upload the collected exam data to the Cloud Dashboard for rapid interpretation by a qualified medical professional. Securely transfer data from to 3rd party systems such as PACS and EMR to facilitate documentation and billing compliance.


Physicians and supervisors can quickly evaluate training exams and real clinical studies via automated templates and digital communication features. Spend less time on documentation, and more time caring for patients.

Use Cases

ThinkSono in Action

Ultrasound is the least invasive and most portable imaging modality in medicine. Although it is a life saving tool, access is extremely limited, negatively impacting outcomes for millions of patients.

Emergency Rooms

Nurses at Oxford University Hospital are using AutoDVT to scan patients on arrival & send the captured images & clips to radiologists for immediate to potentially reduce and/or removing burden on specialist sonographers.

Note this is only used in a clinical study setting and not in normal clinical use.


In the UK, ThinkSono’s technology is can potentially be used as a core component of a redesigned community DVT pathway that includes rapid assessment in primary care settings.

Patients can be scanned locally by their GP without specialist equipment, removing the need to travel to a hospital and/or book multiple appointments.

Note: Currently not being used in practice. The above is highlighting potential uses in the future.

Point of Care / Bedside

In the US & Germany, ThinkSono AutoDVT is being used on medical wards to assess patients for DVT, eliminating the need to transfer complex patients to the ultrasound service.


DVT is a significant problem for the NHS. Not only from a financial perspective, but also a clinical perspective…Pathways for DVT is consequently very time consuming because the patient has to be sent to radiology for the performance of the scan. Enabling nurses, GP’s and other non-specialists to diagnose DVT accurately at the point of care would be extremely useful for the NHS and much more convenient for patients.

The burden of deep vein thrombosis is significant for the National Health Service and one particular problem is that a DVT is suspected much more often than it is found. Potential for non-experts to perform diagnostic ultrasound could dramatically improves DVT diagnostic pathways.

Consultant Haematologist at Oxford University Hospital

I’m excited about this technology and can see many applications for it. For example, rehab units and nursing homes frequently have multiple patients who need venous studies. Their solution is seldom efficient, and I could see every facility like this having the system so they can check their patients whenever they want.
